Hello. While I was at a retail store, I was looking around in the pets area and I spotted this Neptune Stickable Fish Food for £1. I thought that it might be easier to feed the neon tetras while cycling so if there is any uneaten food, it will stay stuck on the glass for me to remove, rather than dropping pellets (some floating and some sinking) in the aquarium. What are your thoughts on this product? Thank you.
